North Dakota boat and trailer registration requirements and fees can feel confusing, especially with different rules for motorized vs. non-motorized boats and trailers. Whether you're a resident or just visiting, knowing what applies to your setup saves you from fines and hassles at the ramp.
As of 2026, all motorized boats and most trailers over 1,500 lbs GVWR must be registered in North Dakota. The process varies by boat length, propulsion type, and whether you need a title.
Quick Answer
North Dakota requires registration for all motorized boats and sailboats over 12 feet. Trailers over 1,500 lbs GVWR need registration too. Fees start at $20 for small boats and $15 for light trailers.
Titling is mandatory for boats 14+ feet and trailers over 1,500 lbs.
Do You Need to Register Your Boat or Trailer in North Dakota?
If your boat has a motor, it needs registration. Non-motorized boats under 12 feet are exempt unless they're sailboats. Trailers must be registered if their GVWR exceeds 1,500 lbs or they have multiple axles.
For out-of-state visitors, you can use your home registration for up to 90 days. After that, you'll need to register in North Dakota. Temporary 30-day permits are available for $10 if you're testing or temporarily using a boat.
What’s the Difference Between Registration and Titling?
Registration proves your boat or trailer is legally allowed on public waters and roads. Titling proves ownership.
In North Dakota, titling is required for:
- Boats 14 feet or longer
- Trailers with a GVWR of 1,500 lbs or more
Registration without titling applies to smaller boats and lighter trailers. You'll receive a registration card and decals for your boat, while titles are separate paper documents.
North Dakota Boat Registration Requirements by Type
Motorized boats of any size must be registered. This includes electric trolling motors. Non-motorized boats only need registration if they're 12 feet or longer, or if they're sailboats regardless of length.
For trailers, the key factor is GVWR. Any trailer with a GVWR over 1,500 lbs must be registered. This includes most boat trailers designed for medium to large watercraft.
Single-axle trailers under 1,500 lbs GVWR don't require registration.
Out-of-state boats can use their home registration for up to 90 consecutive days in North Dakota. After that period, you must register in North Dakota. Temporary permits are available for non-residents who need to test a boat before purchase or for short-term use.
North Dakota Trailer Registration Requirements
Trailer registration depends on two main factors: GVWR and axle count. All trailers with a GVWR of 1,500 lbs or more must be registered, regardless of axle count. Trailers under 1,500 lbs GVWR with a single axle don't need registration.
For titling, the threshold is the same: trailers with a GVWR of 1,500 lbs or more require a title. This applies even if the trailer is only used for personal, non-commercial purposes.
To find your trailer's GVWR, look for the manufacturer's plate or sticker, usually located on the trailer frame near the tongue. This plate will display the maximum weight the trailer is rated to carry, which determines your registration requirements. For more information, you can refer to the North Dakota Department of Transportation.
Step-by-Step: How to Register Your Boat in North Dakota
First, gather your documents. You'll need proof of ownership like a bill of sale or manufacturer's certificate of origin. For used boats, include the previous registration or title.
Next, complete the application. Forms are available online from the North Dakota Game and Fish Department or at local offices. Include your boat's hull identification number (HIN) and any required fees.
Submit your application in person or by mail. Processing typically takes 10 to 15 business days. You'll receive your registration card and decals by mail once approved.
Step-by-Step: How to Register Your Trailer in North Dakota
Trailer registration goes through your local county treasurer's office. Bring your trailer's title or manufacturer's certificate of origin. If the trailer is used, you'll need the previous owner's registration or title.
Provide the trailer's vehicle identification number (VIN) and GVWR. Pay the appropriate fee based on your trailer's weight class. You'll receive your registration and plates on the spot in most cases.

Where to Register: Game and Fish vs. County Treasurer
Boat registration goes through the North Dakota Game and Fish Department. You can submit applications online, by mail, or in person at their offices. They handle all watercraft-related registrations and titling.
Trailer registration is different. It's managed by your local county treasurer's office. They process all vehicle and trailer registrations, including boat trailers.
Common Mistakes That Lead to Fines or Delays
Forgetting to register a motorized boat is the most common error. Even small electric trolling motors require registration. Operating an unregistered boat can result in fines up to $250.
Another frequent issue is missing the GVWR threshold for trailers. Many assume small trailers don't need registration, but any trailer over 1,500 lbs GVWR must be registered. Always check your trailer's weight rating.
Late renewals add unnecessary costs. The 10% late fee applies after 30 days past expiration. Set reminders to renew before your current registration expires to avoid penalties.
What Happens If You Don’t Register?
Operating an unregistered boat on public waters is illegal. Law enforcement can issue fines up to $250 for this violation. You may also be denied access to public boat ramps.
For trailers, driving with an unregistered trailer can result in traffic citations. The fine varies by county but typically ranges from $50 to $150.
Renewing, Transferring, or Replacing Registration
Boat registrations in North Dakota are valid for three years. You'll receive a renewal notice by mail before your current registration expires. Renew online, by mail, or in person with the Game and Fish Department.
Trailer registrations renew annually. Visit your county treasurer's office to renew. Bring your current registration and payment for the new year's fees.
To transfer registration after a sale, the new owner must submit a new application. Include the bill of sale and previous registration. For boats, this goes to Game and Fish.
For trailers, visit the county treasurer.
If you lose your registration or decals, request replacements immediately. Boat replacements cost $5. Trailer replacements vary by county but are typically $5 to $10.
